Our heavy-duty mechanical Murphygage® products combine accurate and reliable indication of engine coolant, air and oil temperatures. Swichgage® models also provide output contacts for fault alarm/shutdown protection. Features include:

• Rugged industrial rated diaphragm movement
• Plated steel or polcarbonate case options
• Polycarbonate lens
• Bright or black stainless steel bezel options
• Tough PVC-armored capillary

The products are available in 2, 2.5 and 4.5 inch (51, 64, and 114 mm) gauge diameters. The 4.5-inch version also features a dial mechanical/analogue readout and adjustable high and low limit contacts.

Our “A-series” (A20T and A25T) temperature Swichgages include environmental sealing to keep out damaging condensation, with two wire (insulated return) switch circuits for marine or mobile equipment use.

Also included here are temperature fault switches, exhaust pyrometers, temperature scanners, thermocouple sensors and thermowells. For ECU/CAN/J1939 engine temperature gauges, click here.
